The constitution is a bill of Negative rights. All of these elections were held illegally and therefore are null and void. The state legislatures have the power to run and hold and certify elections as they see fit. If states do not certify or do not cast electors then you would need the majority of the remainder, which trump has and is why there was a hijinx in these states that were so blatant. Trump won by a blowout and why this is so apparent. In the end, I believe they decertify the elections that were tainted. There is plenty of precedents on what is done on a legislative end of the government, it would only seem natural that it would carry over to the executive branch. Furthermore, the simple act of decertifying would also put 3 if not 4 senate seats back in play as well as a few house seats, for example, Sean Parnell. If you can get control of the congress with strong leadership like Jim Jordan and Ted Cruz in charge, I think there is a workable solution. Otherwise, you always have the constitutional convention route where we lead 36 states to 24, and that 36 states are a supermajority. Lastly, one order of business should be to nullify the 17th amendment. That is where the entire constitution derailed and giving states back their voice in government should be a priority to stop the insanity. The senate would have 72 republican senators at this juncture if state houses were represented in government IMO and we would not even be here.
